Version control

The versioning app expires old versions automatically to make sure that the user doesn’t run out of space. This pattern is used to delete old versions:

For the first second we keep one version
For the first minute Nextcloud keeps one version every 10 seconds
For the first 24 hours Nextcloud keeps one version every hour
After the first 30 days Nextcloud keeps one version every week

The version app never uses more that 50% of the user’s currently available free space. If the stored versions exceed this limit, Nextcloud deletes the oldest versions until it meets the disk space limit again.
